Polar cold is spreading across Canada at the end of 2017 and will remain there until the beginning of the new year. Environment Canada issued extreme cold warnings for most of the Prairies and several other provinces in the country.
This morning, the mercury plummeted to 22° below freezing in Montreal and -25°C in Quebec City, where the seasonal norms are -15°C during the day. The mercury reads -25°C in Ottawa, -20°C in Calgary, -29°C in Yellowknife and -31°C in Whitehorse.
With a temperature of -39 felt in Quebec , party-goers had to dress warmly for their holiday outings on the night of Tuesday to Wednesday.
The Montreal record for December 27, which is unlikely to be threatened today, was set in 1993 with -30.6°C.
The Montreal area is expected to approach an extreme cold warning – a temperature of -38 with wind chill – next night, according to Environment Canada meteorologist Alexandre Parent.
The cold wave is expected to last until January 2nd. Despite a drop in the intensity of the winds, the mercury will still oscillate around -17 and -18 ° C as the weekend approaches.
“What’s important is not necessarily the low temperatures in terms of daily values, but rather the range,” says Parent. Both the geographic extent – it’s almost a cold snap across Canada as a whole – but also a range in terms of time. The end of the year and even the beginning of 2018 may be about ten degrees below the normal of the season. ”
In Quebec, the Abitibi-Témiscamingue, Laurentides and Saguenay-Lac-Saint-Jean regions are also targeted by extreme cold warnings. Same scenario for Alberta, southern Saskatchewan, Manitoba, Ontario and New Brunswick.
An extreme cold warning is issued when wind chill is a high health hazard. Frostbite or hypothermia can quickly occur.
In Nova Scotia, just under 8,000 residential and commercial customers were still powerless early Wednesday morning after the winter storm swept the Atlantic provinces at Christmas.
In total, around 158,000 customers were deprived of electricity . This equates to almost one-third of the approximately 507,000 clients in the province.
